I finally got all the bugs worked out of my car today. Got the tps set right and got it to quit throwing codes and drinking so much gas. I also fixed a few other things and it was running fine. Took it on the interstate and it was driving great, all of a sudden I gave it a little more gas while going uphill and the car started shaking pretty violently like it didn't want to go. I backed out of it and stayed on the gas easy and everythign was fine. It did the bucking/hesitating thing several more times when I gave it more throttle than it liked. after i drove it really easy for a few minutes, it went back to driving like normal, nothing wrong, ran great all through the powerband. I checked codes when i got back and it didn't throw anything. What could possibly cause this?

Plugs or maybe the wires. A lot of the time its the TPS but no codes so.

 

Check for clogged fuel filters also....Particularly the in-tank filter...

 

the plugs are almost brand new so i doubt it's them. I'll check out the wires and the in tank filter this afternoon. I just replaced the in line filter so i know it's new.
